2024 Science & Research Breakfast Seminar Series
Wednesday 6 March 2024
2023 NSW Scientist of the Year, Emeritus Professor Trevor McDougall
What the Ocean tells us about Climate Change
The ocean is an integral part of the climate system, absorbing 30 per cent of our carbon dioxide emissions and 90 per cent of the heat received by our planet due to the increasing concentrations of greenhouse gases.
In doing this, the ocean has been performing a huge service for humanity by moderating the effects on our climate caused by the burning of fossil fuels.
The ability of the ocean to absorb heat in one location and deliver it to another is especially important to understand in the present epoch of increasing temperature, humidity and climate extremes.
In this seminar, internationally renowned oceanographer Emeritus Professor Trevor McDougall will explain the physical principles that underlie our understanding of greenhouse-induced climate change.
Trevor will summarise recent breakthroughs in physical oceanography, explaining what parts of ocean science we know reasonably well and what aspects are poorly known. He will investigate critical questions about what the future holds, including looking at the causes of sea level changes and whether the sea level can be made to stop rising.
Join us for the first Science & Research Breakfast Seminar of 2024, when NSW Scientist of the Year, Emeritus Professor Trevor McDougall presents, ‘What the Ocean tells us about Climate Change’.
About the Speaker
Emeritus Professor Trevor McDougall AC FRS FAA
Trevor is globally recognised as a leading expert in the field of physical oceanography and is the world’s foremost authority on ocean thermodynamics. He has been recognised for his contribution to our understanding of the fundamental physics of the ocean, including how it moves and how it mixes. His ground-breaking research has impacted all of physical oceanography, including observational oceanography and ocean modelling, and he has also transformed the field of ocean thermodynamics.
Trevor's research focuses on the ocean’s role in climate, ocean mixing processes and the thermodynamics of seawater. His major discoveries have positioned Australia at the forefront of ocean physics and climate research. His work has improved the modelling of the effects of climate change and has led to the discovery of several new ocean mixing processes, and the development of new methods of analysing oceanographic data.
Trevor’s theoretical discoveries underlie the adoption of the Temporal Residual Mean parameterisation by ocean and climate models. Widely regarded as the most substantial improvement in ocean modelling since 1985, this breakthrough incorporates the effects of mesoscale ocean eddies in climate models. His dedication to advancing ocean modelling techniques has not only expanded our understanding of the coupled atmosphere-ocean-ice climate system but has also opened new avenues for future research.
Trevor’s contributions to the field of oceanography includes leading an international group of researchers in redefining the 30-year-old definition of seawater thermodynamics and improving the accuracy of the treatment of ‘ocean heat content’ by a factor of 100.
